THEODOR SOHBEPPEL, or SAN FRANCISCO, CALIFORNIA.

MITERINVG-MACHINE,

SPEGIFICATTON forming part of Letters Patent No. 223,819, dated January2'7, 1880.

Application filed July 31, 1879.

To all whom it may concern:

Be it known that 1, THEODOR SOHREPPEL, of the city and county of SanFrancisco, in the State of California, have made and invented a new anduseful Mitering-Machine, which invention is fully set forth anddescribed in the following specification, and the accompanying drawingstherein referred to.

My invention relates to certain improvements in the construction ,ofmitering-Inachines for cutting picture-frame moldings to the requiredbevel; and it consists in the combination, with the cutters, ofadjustable gages to regulate the width of the cut, and in the generalconstruction and arrangement together of the parts of the machine, allwhich will be more fully set forth and described hereinaftr.

In the drawings herein referred to, Figure 1 is an elevation, inperspective, of my improved machine. Fig. 2 is a side elevation;

Fig. 3, a plan view; and Fig. 4 isa detail,

' In this machine a horizontal bed-plate has.

a slot, in which a plate carrying inclined knives or cutters is causedto reciprocate by means of a rack secured thereon and a segmentgear onthe end of a pivoted lever. The cutte'rs are placed at each end of thereciprocating plate, and their inclined cutting-edges are set inopposite directions. Each cutter has an adjustable gage-plate situatedin front of its Cutting-edge, and adjusted toward and back from the lineof the face of the cutter by means of a thumb-screw. Adjustablegage-blocks on the bed-plate, back of the cutters, are arranged to beset at any required angle to cut bevels for octagon and other shapedframes.

- In the drawings, A is the bed-plate; B, the reciprocating plate; 0 (l,fixed brackets thereon for holding the cutters; D D, the knives orcutters, secured in position by bolts which pass through slots in thebrackets; and E E, the adjustable gages, held in place by thethumb-screws F F and the ribs on the plate B. G G are the gageblocksupon the bed-plate,

for holding the picture-moldings at the required angle in presenting theends to the cutters.

The part A of the bed-plate that holds the plate B in place isadjustable by the slots and set-screws, so that any wear may be taken upand the cutters caused to work smoothly without springing.

The cutters can be readily taken off for sharpening and set forward asthey wear down.

The gage-plates in front of the cutters allow the size of the shavingsor cuttings to be regulated and the amounts to be taken off the end ofthe molding to be graduated at pleasure.

The reciprocating plate B is cut away at each end in front of thecutters, so that an open space, I), is provided, to catch and carry outthe Chips and shavings beyond the ends of the machine as the platereciprocates, by which the cutters and their reciprocating plate areprevented from being clogged or choked.

As thus constructed, my machine is operated in the following manner: Thelever is grasped bythe right hand of the operator,

while the molding is laid against the gageblock with the left hand andpressed forward until the end thereof comes in contact with the face ofthe gage-plate in front of the cutter. The molding is then held whilethe lever is oscillated and the cutter caused to act against the end .ofthe molding. The opposite end of the molding is then cut by simplyreversing it and placing it against the other gage block. No change ofposition, therefore, on the part of the operator is required, and thework is performed with greater facility and a saving of time.

Having thus fully described myinvention, what I claim, and desire tosecure by Letters Patent, is

1. In combination with the plate B, having the stationary part A of themachine, all constructed and combined together to operate sub- 10stantially as described and specified.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of June, 1879.

THEODOR SGHREPPEL.
